This is basically an empty subclass of WebappResourceLoader that exists
merely for backwards compatibility with VelocityTools 1.x. Please
use WebappResourceLoader directly, as this may be removed
in VelocityTools 2.1.

WebappLoader

init

This is abstract in the base class, so we need it.
NOTE: this expects that the ServletContext has already
been placed in the runtime's application attributes
under its full class name (i.e. "javax.servlet.ServletContext").
